Troponin — Cardiac Marker: Normal Range, Causes of Elevation

Updated: June 2025

Troponin (I and T) are cardiac muscle proteins released into the bloodstream upon myocardial damage. The primary marker for acute myocardial infarction with high specificity.

Reference Range

< 0,04 нг/мл (тропонин I), < 14 нг/л (высокочувствительный тропонин T)

Causes of Elevation

• Acute myocardial infarction
• Unstable angina
• Myocarditis
• Cardiomyopathy
• Pulmonary embolism
• Sepsis with myocardial involvement
• Renal failure (moderate elevation)
